The following special issues are scheduled for publication in GI:
The Earth's magnetic field: measurements, data, and applications from ground observations (ANGEO/GI inter-journal SI)
01 Nov 2016–03 Mar 2017 | Guest editors: J. Rasson, A. Gonsette, K. Arora, A. Chulliat, C. Turbitt, and V. Korepanov | Information
This special issue addresses open research topics related to ground observations of the Earth's magnetic field. It consists of papers based on talks given during the XVIIth IAGA Workshop on Geomagnetic Observatory Instruments, Data Acquisition and Processing that was held in Dourbes (Belgium) from 4 September to 10 September 2016. Ground magnetic observatories are important for geomagnetism. They provide fixed, long-term, high-quality global time series, thus helping the scientific community to understand the geophysical processes of solid Earth as well as the interaction of the Sun with Earth's magnetosphere and ionosphere. Data users such as space weather, space physics, and geomagnetic field modelling communities always require better quality data from observatories for their applications. This workshop aimed to improve observatory practice especially when faced with new challenges like advanced instrumentation development, higher sampling rates, faster definitive data processing, real-time delivery, and remote deployment. The event was successful in bringing together about 90 attendees from 37 different countries, of which 21 were European. The 72 presentations covered topics such as instrumentation, observation techniques and processing, data transmission, and applications. We invite the workshop participants and other researchers to submit their results to this inter-journal special issue of Annales Geophysicae (ANGEO) and Geoscientific Instrumentation, Methods and Data Systems (GI).
Observations and Modeling of the Green Ocean Amazon (GoAmazon2014/5) (ACP/BG/AMT/GMD/GI inter-journal SI)
01 Jun 2015–31 May 2018 | Guest editor: W. Schmidt | Information
Observations and modelling of the Green Ocean Amazon (GoAmazon2014/5): the GoAmazon2014/5 campaign sought to quantify and understand how aerosol and cloud life cycles in a particularly clean background in the tropics were influenced by pollutant outflow from a large tropical city. The project addressed the susceptibility of cloud–aerosol–precipitation interactions to present-day and future pollution in the tropics. The experiment took place in central Amazonia from 1 January 2014 to 31 December 2015, including intensive operating periods and aircraft in the wet and dry seasons of 2014.
